RESILIENT WHEEL.

To all whom it may concern Be it known that we, ADAM F. GLASER and l0-HN OLSEN, citizens of the United States, and residentsot' Jersey Cit-y, Hudson county, New Jersey, and W hippany, Morris county, New Jersey, respectively, have invented ciertain new and useful Improvements in Resilient Wheels, ot' which the following is a specification;

(hir invention relates `to improvements in resilient wheels wherein an axle is resiliently `conm-icted with the wheel hul), whereby the axle and hub may have movement relatively to cach other, means being provided for causing the axle to rotatevthe huh, or vice versa, while maintaining resilient relation to each other, and our invention h: particular reference to improvements in A"the class ot' resilient wheels shown in United States Letters Patent No. 912,305, issued to us 'Feh-l ruary 1G, 1909.' l

The natnreof our invention will be more tally hereinafter set forth and then pointed out in the claims.

ltet'erence is to be had to the accompany-- ing drawings forming part hereof. wherein,

Figure l is a side view of a wheel embody ing onr invention; Fig. "2 is an renlarged sectional view of the central portion ot the wheel, and Fig'. 5l is an enlarged section, snhstantially on the plane ot' the line 53, I... in Fig. 1.

Similar numerals ot reference indi .ate con respondingv parts in the several views.

rllhe numeral l indicates a hollow hub or casingf ot any suitabh` construction connected with spokes 2 in any suitable or well -ltnown manner, and at il is an axh` adapted to have tree movement in all directions within opening' 1tL in one ot the walls 1" ot" the hub or casino'.

At Il is a head or cam member located within halo or casing 1`r to which head or cam member axle il is to be attached in any snitahle manner, as hy a key. Thev cam surfaces or faces 4F ot head 4 are in angular torni with relation to each other. ln the example shown in Fig. 2 the earn or working Jfaces LL of head 41- are shown inthe form ot an equilateral triangle.' although it will he nn.- derstood that the working' iam faces ot head 4 may have any other suitable form.

Hub or casing 1 is provided with guideways 5, shown disposed on opposite sides oi. the axis ol" the hub, said guideways being Specification of VLetters Patent.

slide in goideways 5 and adapted to bearagainst. the corresponding taees Lld of head 4,

the springs (S being shownlocated within` and acting with the thrust pieces or pistons4 7 to hold 4the latter against said cam faces. T he springs 6 also co-act with hub or casing 1. for which purpose we have shown screw` plugs S meshing' with threads 5 in guideways or cylinders 5 whereby said blocks con neet' the springs operatively with the huh or casing. By screwing blocks 8 into the cylinders more or less the tension of the springs may be regulated as desired,' and the plugs S may he removed for ready replacement oit the springs. 'W e have shown the thrust pieces or pistons 7 as provided with heads 7 ot such dime sions to prevent said thrust pieces or pistons trom sliding;` ont of their Ke'iiideways or cylind 5 in an out-ward di rt'rction. d .alle plagen., 8 are a convenient means tor connecting` springs G with hnlo or casing' 1, other means may be provided for this purpose it desired. Head 4 is shown provided with a flange or disk-like portion Lil" adapted to tit and slide alongthe inner tace at' wall l and close opening l, and said head il is also shown provided with a fiange or dislelilte portion LLC at the side opposite the flange 4b, between which flanges the thrust pieces or pistons 7 tit freely. Huh or casingl is also shown provided with an opening- 1 on the side opposite openii'igflaof siil'licient iliinensions to permit the entrance ot head -l and its flanges, and the opening` lC is main tained closed by a block or plug l0 shown provided with threads 10ftmeshingr in dorresponding` threads in the wall of opening i, although the closure 1.() may be otherwise e- ,enred to hub or casing; 1. `hc sides ot hlocliv ll or its flanges et", Ll in conjonction with walls 1b, l of the hulo or casing 1 resist side thrust ot head t.i for which purpose 'elosure or blwfl l() may be set as close to the. corresponding surface ot' head il and its flange fl-c as desired.

The springs G will .serve to normally malntaii'i the head yit and the axle substantiallyv axially with respect to hub or casing l by reason ot the correlation of the various 'disposed head parts. lVeight upon the axle will be correspondingly resisted by the springs, as such weight is transmitted through head 4t to said springs, and when the axle is rotated the cani faces of head 4 acting through thrust pieces or pistons 7 against the springs will' be resisted by said springs, *andv t-he thrust pieces or pistons 7 in their guideways will transmit rotary motion to the hubV and wheel or vice versa. When the wheel meets obstructions or 'depressions in the road the shock will be relieved or absorbed and the axle correspondingly relieved Vfrom shock as the axle has free movement within the hub or casing, land the cam faces of head 4 may slide with respectto thrust pieces or pistons 7, such sliding of said thrust pieces or pistons being resisted by the springs while the tendency of the springs in connection with the thrust pieces or pistons and the cam faces of the head to restore or maintain the axle in proper operative position. By having three springs arranged radially at 120o apart with a corresponding triangularly interposed between said springs the tendency is for one or more of the springs to always resist the weight or load, and as the cam-faces of the head in certain positions of the wheel tend to slide between two thrust pieces or pistons 7 the weight or strain'will be transmitted to the corresponding springs. As the arrangement of head 4 or its cam with respect to thrust pieces or pistons 7 is such that said head cannot revolve independently or between said thrust pieces or pistons owing to the 'resistance of the springs the hub will necessarily be rotated by the head, or vice versa.

While we have illustrated a convenient formof our invention it will be understood that the .same is not limited to the details of construction and arrangements shown and described, as the same may be varied, within the scope of the appended claims, without departing from the spirit of our invention.

Having now described our invention what we claim is: v

l. The combination of a hub provided with an opening to permit free movement of an axle therein, a head for the axle Vprovided with triangularly disposed faces, thrust pieces eo-acting with said faces,

and springs interposed between the thrust' pieces and the hub.

2. The combination of a hub provided with an opening to permit free. movement of an axle therein, a head for the axle provided with triangularly disposed faces, thrust pieces to co-act `with 'said' faces, means for operatively connecting said thrust pieces with said hub, andsprings interposed between the thrust pieces and the hub.

The combination of'a hub provided with an opening to permit free movement of an axle therein, a head for the axle pro vided with angularly disposed cam faces, thrust pieces co-acting with said faces, said head havin ianges on opposite sides of said cam aces, the Athrust pieces .being located betweenl said ianges, said hub havingfaces co-acting with said flanges,springs interposed between the thrust pieces and the hub, and means retaining said springs in place.
